by means of apertures in preferably provided with partition d, by w there are recesses e in said housing, ing a greater distance apart The inner end and central partition d with apertures other. of each housing` are provided the outside of the car that extend through the Eachhousing is also a central transverse hich it is strengthened, and the longitudinal inner those in one edge bethan those in the engaged by a rod C, and the adjacent extremity coils f of a recesses in the housings in one of this rod is caught in a end of said housing.

spring-wire that engages a the inner longitudinal edges B, this wire being direction from said housings recess in the other The rod extends through ll the of bent to form the Opposite direcbeing of different sizes, one Within the other. and angularly bent to form a handle j for the smaller angular yoke, and an outer kink k in said wire serv'es as a handle for the larger angular yoke.

The spring-wire yokes are under tension toward the car, and cards caught between either or both yokes and said car will be securely heldin place. It is also practical and within the scope of our invention to make a clamp comprising but one housing, rod or pin, and spring-wire yoke'.

By having freight-cars equippedwith cardclamps in accordance with our invention the placing and removal of accompanying informationcards can be expeditiously performed, especially in coldweather, it only requiring the pulling back of a spring yoke or yokes, manipulation of a card to put it in or out of the desired position, and a release of said yoke or yokes.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. A card-clamp comprising a housing attachable to a support and provided with a central transverse partition, a rod or pin engaging the ends and partition of the housing, and a spring-Wire yoke having pin or rod supported coils inside the housing.

2. A card-clamp comprisinga pair of housings attachable in line to a support and each provided with a central transverse partition, a rod or pin engaging the ends and partition of each housing, and a spring-wire bent to form rod or pin engaging coils inside the housings, bows extending in one direction and yokes of different sizes one within another extending from the a direction opposite that of the bows.

In testimony that we claim the foregoing we have .hereunto set our hands, at Milwaukee, in the county of Milwaukee and State of Viss cousin, in the presence of two witnesses.
